표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

Disposal of a homicide victim by dismemberment is rare, but individual cases are on record in most major medicolegal departments. Recognition of postmortem mutilation may be of importance in the interpretation of certain murders committed by sexual perverts and other mentally deranged individuals and sometimes performed for the sole reason of easier disposal of the body. Postmortem dismemberment is usually readily recognizable as such; The edges of the injuries are dry and lack evidence of bleeding. The joints may be disarticulated without fracture, or the use of an axe or saw may be evident from examination of bones. Parallel horizontal or oblique furrows in the bone surface are caused by skipping of the saw prior to establishing depth. Such patterns on the bone may assist in identifying the particular saw involved. So we report 25 dismembered corpses that autopsied in National Institute of Scientific Investigation. This paper can help in attempting to establish not only the first criminal investigation steps but also the medicolegal approach methods in unidentified and dismembered deaths.

The purpose of this study is to examine in details the effects of the constructive instruction on the acquisition of scientific conceptions and the problem solving of Science based on ICT (Information and Communication Technology). In this study, An examination tool developed for a previous learning concept was applied to instructional model by a constructivism to students, and by grasping a previous learning concept and using ICT. An way of the improvement about acquisition of scientific conceptions and problem solving of subject was inspected, the rate of a correct answer, the decrease rate of misconception, and the achievement rate of a periodical examination were compared. The result of such enforcement was as follows; The motivational induction for learning, the interesting rate, and the rate of a correct answer in an experimental group showed highly. The result of a examination between an experimental group and a comparative group showed similarly. The rate of accomplishment also showed highly in an experimental group. Accordingly, the constructive instruction using ICT proved to be fit for seventh educational course as a student-centered course. The change of recompositional course for knowledge from a previous learning concept to a new one showed clearly.

Shotguns were developed as an alternative to single-missile rifle or handgun in order to enable gunner to spray a wide area with shot and thus kill birds and small animals too difficult to hit with single-missile weapons. As the popularity of shotguns grew, ammunition was developed for large game. The use of shotguns on humans has been markedly increasing in various manner of death. In forensic aspect, the shotgun wonds gave characteristic findings due to their own characteristics and medical examiners may determine the range, distance, direction and kinds of gun. When the muzzle of the shotgun is placed tightly against the surface of the abdomen or thorax, the consequent wound of entrance will be single in number and circular in shape, and will have a diameter approximately equal to that of the bore of the weapon. However, when the wound is made over a site with underlying bone, especially in the scalp, the wound may have a different appearance, showing star shaped entracce due to short to mid-range, considerable variation occurs in the appearance, showing star shaped entrance due to tears from the sides of the wound and accompanying soot and burn effect. When the muzzle is held short to mid-range, considerable variation occurs in the appearance of the wound. We report two cases of shotgun wounds which showed typical findings of contact shots and distant shots.

This study first investigates the concept and the meaning of centrality from the viewpoint of CHe-Yong-Sang theory as applied to architectural space and secondly investigates the way in which the centrality of modern urban dwelling space is perceived. The findings indicate that the centrality of modern urban dwelling space is perceived in more complex manners than is the case with the traditional dwelling space. While the centrality of dwelling space is observed at different locations, its significance persists in the urban dwelling space.

백혈병환자에서 Liposomal Amphotericin B로 치료된 파종성 Fusarium 감염 1예

Fusarium spp.는 사람에서 드물게 각막염, 조갑진균증, 상처나 화상부위감염 등을 유발하는 것으로 알려져 있으나 최근에는 면역저하자에서 기회감염의 원인균으로 증가하고 있는 추세이다. 면역저하자에서 파종성 감염이 있는 경우에 예후는 치명적이나, 증례가 많지 않고 진단방법이 제한되어 있어 조기 진단과 신속한 치료가 쉽지 않다. 그러나 특징적으로 피부병변의 동반이 흔하여 면역저하자에서는 피부 병변의 면밀한 관찰과 함께 Fusarium 감염을 조기에 의심하여 피부생검이나 배양을 하는 것이 진단에 도움이 되리라 생각된다. 파종성 Fusarium 감염의 치료로는 감염 부위의 국소적 외과적 절제와 전신적 항진균제의 사용이 필요하고 현재까지는 amphotericin B가 비교적 효율적인 항진균제로 알려져 있으나 면역저하자에서 이에 반응을 하지 않는 경우가 많다. 저자들은 급성골수성백혈병 환자에서 관해유도화학요법 시행 후 호중구감소상태에서 피부병변과 폐침윤이 발견되었고 피부의 중심부 궤양을 동반한 구진성 병변에서 배양검사를 통해 파종성 Fusarium 감염을 진단하였으며 liposomal amphotericin B (AmBisome )를 사용하여 성공적으로 치료한 예를 경험하여 보고하는 바이다. Fusarium spp., basically a superficial pathogen, is a newly emerging fungal pathogen of opportunistic infections in immunocompromised patients. At present, although Fusarium spp. are relatively resistant to amphotericin B, the combination of amphotericin B and surgical debridement appear to be optimal treatment for disseminated infection. Recently we experienced a 32-year-old neutropenic patient after induction chemotherapy for acute myelocytic leukemia presented with skin lesions and infiltrations in both lungs. We diagnosed with disseminated fusariosis by skin culture and successfully treated the patient with liposomal amphotericin B. We emphasize a high index of suspicion for skin lesions especially in immunocopromised patients.

Congenital pulmonary lymphangiectasis is a rare cause of severe respiratory distress in the newborn period and most of these patients die, usually within the first 24 hours of life. The light microscopic characteristics of the lungs are a network of partly tubular, partly cystically enlarged lymph vessels with-in large areas of connective tissue and they have thin walls lined by endothelium. Also congenital pulmonary lymphangiectasis is closely associated with cardiovascular malformation, and most frequently occurs in the clinical setting of congenital heart disease with or without pulmonary venous obstruction(total anomalous venous return, atresia of large pulmonary veins). The authors describe three typical cases of congenital pulmonary lymphangiectasis.

Architectural space consists of both artifactual contents and physical settings interwined to each other. Basic relationship between content and form can be compared to dual structure of language, D-structure and S-structure. If architectural space is indeed the language of design, it can be understood form semantic Level, furthermore, a dubious relationship between two poles can be articulated by the use of design semantics.

디버링 작업을 위한 로봇 제어기 개발

이중훈,박근우,이성학,이민기 國立 昌原大學校 産業技術硏究所 1999 産技硏論文集 Vol.13 No.-

This paper presents the controller of a double parallel robot manipulator applied for deburring work. This is one of the least favored works because of dust, noise, vibration, and accidental injury. A serial robot manipulator has been limitedly applied to light-load deburring work due to the poor stiffness of the manipulator. A double parallel robot manipulator has been developed for a strong rigidity by stacking two parallel mechanisms. It can be applied to heavy-load deburring work with high stiffness. To apply the robot to cut the burrs on a unknown geometric surface, this research will develop an intelligent controller to measure bur track and cut it with a constant cutting force.
